who dialed 911 to complain about charlie sheen's behavior? the real-life hollywood drama. man, rough life for charlie these days. >>> but before we get to that, of course, to egypt, a tense, angry and politically charged nation this morning. >> it seems neither opponents nor the supporters of president hosni mubarak will step down. >> abc's alex marquardt is in cairo now with the very latest. good morning to you, alex. >> reporter: good morning, rob and vinita. it is now 9:30 in egypt. and those who actually managed to sleep last night are waking up to reports of new violence. i'm watching tense scenes on tahrir square right now where pro-government forces are facing off against anti-government demonstrators. i'm watching people breaking big stones into smaller rocks for throwing. there are chants of revolution, revolution until victory. the egyptian government says that five people were killed overnight and 800 were injured. of course, it could be higher. right now there's a relative lull compared to earlier when heavy gunfire broke out in the square before dawn. al jazee
